All safety procedures described here shall be strictly adhered to by all parties servicing and maintaining this
product.
DANGER
Strictly observe the following cautions. Failure to comply could result in serious bodily injury or loss of life.
1. Always disconnect the product from the power source and peripheral devices when servicing the product or
performing maintenance.
2. When performing works described in this manual, do not connect to a power source until instructed to do so.
Connecting to a power source causes high voltage in the power supply unit and some electronic components
even if the product power switch is off. If you need to perform the work with the power cable connected to a
power source, use extreme caution to avoid electrical shock.
WARNING
Strictly observe the following cautions. Failure to comply may lead to personal injury or loss of life.
1. Always wear protective goggles for disassembly and reassembly to protect your eyes from ink in working. If
any ink gets in your eyes, wash your eyes with clean water and consult a doctor immediately.
2. When using compressed air products; such as air duster, for cleaning during repair and maintenance, the use
of such products containing flammable gas is prohibited.
PRECAUTIONS
Strictly observe the following cautions. Failure to comply may lead to personal injury or damage of the product.
1. Repairs on Epson product should be performed only by an Epson certified repair technician.
2. No work should be performed on this product by persons unfamiliar with basic safety knowledge required for
electrician.
3. The power rating of this product is indicated on the serial number/rating plate. Never connect this product to
the power source whose voltages is different from the rated voltage.
4. Replace malfunctioning components only with those components provided or approved by Epson;
introduction of second-source ICs or other non-approved components may damage the product and void any
applicable Epson warranty.
5. The capacitors on the Main Board may be electrically charged right after the power turns off or after driving
motors which generates counter electromotive force such as when rotating the PF Roller or when moving the
CR Unit. There is a risk to damage the Main Board if the Head FFC is short-circuited with the capacitors on
the Main Board electrically charged, therefore, after the power turns off or after motors are driven, leave the
printer untouched for approximately 30 seconds to discharge the capacitors before starting disassembly/
reassembly.
6. To prevent the circuit boards from short-circuiting, be careful about the following when handling FFC or
cables.
When handling FFC, take care not to let the terminal section of FFC touch metal parts.
When connecting cables/FFC to the connectors on circuit boards, connect them straight to the connectors to avoid
slant insertion.

7. In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static
wrist straps, when accessing internal components.
8. Do not tilt this product immediately after initial ink charge, especially after performing the ink charge several
times. Doing so may cause ink to leak from the product because it may take some time for the waste ink pads
to completely absorb ink wasted due to the ink charge.
9. Never touch the ink or wasted ink with bare hands. If ink comes into contact with your skin, wash it off with
soap and water immediately. If you have a skin irritation, consult a doctor immediately.
10. When disassembling or assembling this product, make sure to wear gloves to avoid injuries from metal parts

1.2 Power-On Sequence
This section describes the power-on sequences in two conditions. The preconditions are as follows.
Condition 1: Normal power-on sequence (See Table 1-1.)
Turning on the printer after turning it off without an error.
Initial ink charge has finished and every cartridge has sufficient ink.
No paper on the paper path.
The Printhead is capped with the Cap Assy.
The CR Unit is normally fixed by the Change Lever.
Maintenance error recovery has never been performed.

3-2.The CR Unit moves to the 0-digit side slowly and confirms it touches the Right Frame.
3-3.After the PE Sensor checks if paper exists, the PF Motor rotates clockwise for one second and releases the CR lock.
3-4.While checking if the CR Unit does not touch the Change Lever (CR lock) or the foreign material, the CR Unit
moves to the 80-digit side slowly until it touches the Left Frame.
3-5.The distance from the position where the CR Unit touched to the Left Frame is regarded as the standard distance
from the origin position, and the home position is fixed.
From then on, the CR Unit position is monitored according to the signals from the CR Encoder.
3-6.The CR Unit quickly moves to the ink end sensor detection position on the 0-digit side.
4. Low temperature operation sequence
4-1.The CR Unit moves to the 0-digit side slowly.
4-2.The CR Unit quickly moves back and forth between near the Change Lever and near the Left Frame for two times.
5. Detecting ink cartridge and initializing ink system
5-1.After checking the Ink End Sensor, the CR Unit moves to the ink detection position in the 0-digit side and detects
the ink remaining.
5-2.The CR Unit returns to its home position.

Condition 2: Power-on sequence after recovering from a paper jam error (See Table 1-2.)
Turning on the printer after turning it off with a paper jam fatal error.
There still remains paper on the paper path out of the detecting area of the PE Sensor.
Maintenance error recovery has never been performed.
Table 1-2. Condition 2: Power-on Sequence after Recovering from a Paper Jam Error

Executes No.1 to No.3 on the normal power-on sequence (Table 1-1).
4. Detecting remaining paper
4-1.5.The CR Unit returns to its home position.
4-2.The CR Unit moves to the 80-digit side and confirms there is no paper.
4-3.The CR Unit quickly returns to its home position, and displays on the LCD or with flashing LEDs that the paper jam
error occurs.
When the user removes the paper and releases the paper jam error by panel operation, the normal power-on sequence from No.1 (Table 1-1) is executed

To recover from the maintenance error, the dedicated software that can be downloaded
from the web site which can be accessed from STM3 is required.
The printer operation related to the maintenance error recovery is as follows.
• When the waste ink counter reaches the threshold value (1) for the first time and the
maintenance error occurs, the counter threshold of the maintenance error is changed
to threshold value 2 after performing recovery from the maintenance error.
• After the threshold value (2) is enabled, the warning; to notify the possibility of ink
leakage out of the printer, is displayed every time the waste ink counter increases by
1%.
• If the waste ink counter reaches the threshold value (2), the maintenance error occurs.
Then, the waste ink counter is changed back to the threshold value (1) after recovering
from the maintenance error, and the warning is displayed repeatedly according to the
increment of the waste ink counter until the maintenance error occurs when the
threshold value (2) is reached.
(Recovery from the maintenance error can be performed up to the specified number
of times.)

1.3 Fatal Error Code List
This section describes how to check the fatal error code, description, and the possible causes.
1.3.1 Displaying the Fatal Error Code
The fatal error code is stored in the EEPROM on the Main Board and can be read out using the Adjustment
Program. The code can be displayed on the LCD of the control panel by a special panel operation.
Since SX235W series does not have LCD, use the Adjustment Program to check the fatal
error code.
Only the printer fatal error code can be displayed by this panel operation.
For the fatal error codes, descriptions, and their possible causes, see " 1.3.2 Printer Fatal
Error Code (p15)".
The following describes the panel operation for SX230 series, SX430W series and SX440W series to display the
fatal error code.
Method of displaying the fatal error code
